5 Claims.

Our invention relates to new and useful improvements in apparatus forprocessing material for forming paper. pulp, and the like and isdirected ymore particularly to a beater-renner mechanism.

The principal objects of the invention are directed to a novel andimproved construction of beater-renner mechanism which is constructedand arranged as a unitary and self-contained structure adapted forshipment asa unit or package for installation at the mill.

Heretofore the several components of beaterv apparatus have beenmachined, iitted and assembled at the place of manufacture and thendisassembled for the shipment of the sepa-rate units to the mill wherethey were reassembled. For instance, it has been usual to ship asseparate such units as each stand and lighter-bar, the cross orequalizer shaft, the links, the curb, the cover, the front side, themid-side, the back fall, the motor support, the packing boxes, the roll,the bearings, and the bed plates, etc. At the mill Where the beater isto be used, the units have been uncrated and assembled or erected andthis has always necessitated the sending of skilled erectors to theplant of the purchaser which may be thousands of milesy from the placeof shipment.

The purchaser must provide foundations for the different components towhich the components are secured. These foundations and securing meansmust be disposedA accurately relative to one another in order to tie theunits together in accurate relationship and alignment in order towithstand the shocks and strains resulting from the operation of thebeater and maintain the necessary accurate relationship and alignment ofthe components for operation of the machine.

According to this invention, a complete unitary mechanism is providedwherein the components are assembled or erected in conjunction withsupports and tub forming elements to provide a complete unitarystructure adapted for shipment as a complete unit.

The unit may be shipped to the purchasers plant and placed on a suitablesupport such as a foundation and is in readiness for operation Withoutthe usual erection or assembly. The components of the mechanism beingassembled 2 with supporting structure and tied together in operativerelationship provide a self-sustaining unit Where the correctrelationship and alignment of components is maintained. In this Way.complicated foundation units to which the 'structure must be tied areunnecessary. In fact, the necessary tying together of the components isaccomplished within the structure itself and all that is necessary atthe purchasers plant is a. suitable support which may be a foundation oreven a suitable floor structure. On this the mechanism is establishedand it need not necessarily be secured thereto since shocks, strains andforces in the operation of the mechanism are ab- 1 sorbed andcompensated for within the unitary structure itself and are not, as withprior art structures, transmitted to the supports therefor` As anexample, wih a prior art beater when the roll is in upper position, theload is transmitted to the externally mounted stands and when the rollis lowered most of the load is tra-nsferred to the bed plates so thatdue to the shifting of load it is necessary to securely anchor the unitto a foundation. With the present case, the transfer of load is notexternal to the unitary structure.

The purchaser may construct a beater tub of any desired form around andin connection with the mechanism. This feature ofers a completelyflexible arrangement in that the tub can be built of any type ofmaterial such as tile, concrete, steel or wood. Also the size of the tubcan be readily altered to suit the space aavilable or the demand whichmay be placed for a given batch.

If desired, the tub may be eliminated and the unitary mechanism set upfor continuous processing of stock which is fed thereto at one end anddelivered therefrom at the other, and plural mechanisms may be arrangedin alignment without the tub construction for successive steps in thecontinuous processing of stui.

By reason of the unitary construction, it is possible to provide amechanism which is more efficient in operation and in which thecomponents are at all times maintained in accurate relationship andalignment. Not only is the necessity of sending erectors for erectingapparatus obviated but the shipping difficulties with many separateunits is avoided by the provision of the unitary structure.

As an important feature of the invention, manufacturing costs aregreatly reduced. According to the invention, sheet metal is employedwhich is secured together as by welding to provide a strong rigidsupporting structure for components mounted on and secured thereto. Inthis way costly machined castings are largely obviated.

All of the above objects l accomplish by means of such structure andrelative arrangements of parts thereof, as will fully appear by aperusal of the description'below and by various specific featureswhich-.will be hereinafter set forth.

To the above cited and other ends and with the foregoing and variousother novel features and advantages and other objects of my invention aswill become more readily apparent as the description proceeds, myinvention consists in certain novel features of construction and. in thecombination and arrangement of parts as will be hereinafter moreparticularly pointed out in the claims hereunto annexed and more fullydescribed and referred to in connection with 'the accompanying drawingswherein:

Fig. 8 is a sectional elevational view on the line 8 8 of Fig. 2; and

Fig. 9 is a sectional plan view on the line 9 9 of Fig. 2.

. Referring now to the drawings more in detail, the invention will befully described.

A longitudinal front wall 2 and a longitudinal mid-wall 4, bothvertically disposed, are provided. These will preferably be formed frommetal plate or sheet material. Stainless steel has been found to bedesirable for the practice of the invention as it is capable ofwithstanding the injurious action of the constituents of paper and pulpmaking materials.

The walls 2 and 4 are secured to metal transversely spaced longitudinalhorizontal sole plates 6 and 8` and is preferably accomplished bywelding as indicated at i and El, in Figs. 5 and 6.

The rear wall 4, herein referred to as mid-wall, functions as themid-feather when the unitary structure hereof is used by the purchaserin connection with a beater tub construction.

A transverse base plate lll of metal is provided, see Fig. 4. This plateextends between walls 2 and A4 and at opposite sides is welded theretothereby functioning to provide a base for the bed plate construction andto tie the walls 2 and 4 together. Said plate may be called the bedplate base.

Transverse partitions l2 above the plate I0 have opposite ends securedto the walls 2 and 4 and to said plate l!! as by welding.

An intermediate transverse substantially vertical plate i4 of metal hasa lower end portion I6 and an upper portion I8 with its opposite endssecured to the walls 2 and 4.. The. lQWQI edge. of

.4 portion I6 is welded as at l1 to the plate I il. The plate I4 may becalled the back fall plate.

A lower transverse plate 2l) has a depending portion 22 and the righthand end portion thereof is formed to provide a transverse channel 24.This member has opposite ends welded to the walls 2 and 4 and the loweredge of portion 22 is Welded at 23 to the plate I0. This plate 22 may becalled the front plate.

The plate portions I6 and 22 and partitions l2 provide a plurality oftransversely extending pockets for bed plate boxesv indicatedr by Theseboxes may be of ordinary construction having a plurality of longitudinalcutter bars or knives 28 projecting from upper sides thereof.

The boxes 26 are insertable into the pockets through the front wall 2which is provided with a suitable opening 29 closed by a cover plate 3i)se cured in Aplace by screws or bolts 32, see Fig. 2.

This is usual construction and permits of the boxes being inserted inand withdrawn from the pockets.

Reinforcing members 34 are welded to the member I0 and adjusting screws35 in threaded engagement with the member lil and members 34 engage theunderside of the boxes 25 for adjusting them relative to the beater roll4B.

An opening 42 in wall 2 is provided for access to the adjusting members36 and a cover 44 therefor is secured thereover by screws or bolts 4E.

Pillars for lighter-bar pivots and indicated generally by 50 aredisposed on outermost sides of the walls 2 and 4, see Figs. 2 and 6.Said supports 50 are formed from sheet metal to be channel shape incross section and have outer vertical sides 52, and opposite sides 54and 55 adjacent thereto extending upwardly in converging relation fromthe sole plates t and 8.

The lower ends of the outer sides 52 are secured to the sole plates bywelding at 53. Lower ends of sides 54 and 56 are similarly welded to thesole plates and the rear vertical edges of said walls 54 and 56 arewelded to the walls 2 and 4.

Transversely spaced and vertically extending pivot supports and 62provided at the upper sides of the pillars and horizontal cap plates 64are welded to the supports S and 82 and walls 2 and 4 While the supports6c are welded to portions 52 of the pillars as best shown in Fig. 6.

Pvots 68 are journalled in the supports 62 and 6B by antifrictionbearings'i while caps 'i2 are disposed at opposite ends of the saidpivots.

Reinforcing members lr6 and 'i8 are provided which extend from the s-oleplates into the pil lars. Said members are Ll-shaped and substantiallyalike, the member 'i6 being shown in Fig. 7. Said members have upwardlyextending arms such as 80 as in Fig. 7 which extend lwithin the walls ofthe pillars 50. Lower portions of the reinforcing members are welded tothe sole plates and the side arms thereof are welded to the walls of thepillars and upper supports thereof.

The pillars are filled with concrete indicated by 82 which with thefabricated members provide strong rigid structures suitable forpivotally supporting the lighter-bars carrying the roll 4il.

These pillars 50 are integral parts of the structure and obviate thefoundations heretofore necessary for supports for the lighter-bars inthe necessarily correct relationship to similarly supported othercomponents.

Lighter-bars 84 are provided which have inner ends 8'6 on said pivots68. The said inner ends of the lighter-bars maybe xed on the pivotswhich aorta- 5 are oscillatable in the bearings or the' lpivots may befixed in the members 60 and 72 with the said Alighter-bars oscillatablethereon.

Thelighter-bars yadjacent the pivots are provided with caps B8 securedthereto and which .retain anti-friction bearings 90. End caps 92 closeouter ends of the bearings and inner ends .are provided 'with suitablesealing means :indicated by 94.

Shaft ends 9d of .the roll 4d are journalled for rotation in thebearings 9i). The roll il@ may be of any suitable `form having knives orcutter bars 9.8 for cooperating with the xnives or cutter bars of the'bed plate although the roll of U. S. Letters Patent No. 2,482,712 ofSeptember 20, 194g ,has been found to be `,very desirable for thepractice :of the invention.

The lighter-bars S4 are swing-able up and down to the position of theroll and. its cutter bars relative to those .of the lied plate, bymechanism latei t0 be described.

A hood or cover it@ overlying the roll has flanges 32 and m4 at itssides and ends. The side .flanges rest on flanges lili of the walls 2and 4 and are secured thereto by suitable means, such y,

as 1291s,.

A curving Wall Hi8 extends between walls 2 and 4 partly around the roll4u, see This wall ,may be termed a breast plate and has a flange il@ .onits upper end to which the flange |Ei4 of the cover is secured, as shownin Fig. 4.

Annular members il 2 extend from opposite ends of the roll 4u and havefixed thereto flexible sealing discs l I4 which engage members I itsecured'to opposite sides of the cover Hill around 3- openings H8therein, see Fig. 5. The construcftion is such as to permit rotation andup and down movements of the roll 4Q whilst sealing the roll and cover.

Links V|213 are pivoted at i122 to the forward ends of the lighter-bars84 and upper ends of said links are `pivotcd at |24 to arms ltd of atransverse equalizer shaft |28. Bearing supports such as |30, aresecured to the walls 2 and 4 by means of a ring |32 and bolts |34, seeFig. 8. Shaft E28 is rotatable in anti-,friction bearings |34 in thesupport?.S .|39 and annular caps i3d close said sup- .ports- The arms|2t` are fixed to opposite ends of `the equalizer shaft #2B and thearrangement is such that the lighter-bars swing uniformly or through thesaine angle as one or the other of them is actuated. In this way Isincethe lighter-bars move uniformly by means of shaft |28, the axis of roll40 is maintained on a horizontal axis at all times.

Means for actuating or adjusting the lighterbars disposed adjacent thewall E will be explained with reference to Figs. 2 and 3.

A stand 14d is secured to the sole plate S and and adjusting screw E43is reciprocable therein. A worm gear E44 is rotatable in a housing lfltat the upper end of the stand its and a worm |43 in engagement therewithis fixed on a shaft lli@ which is rotatable in the said housing andcarries a hand wheel |52 on its outer end.

The gear |44 is in threaded engagement with the screw |42 and the upperend of the screw carries a piston |54 disposed in a cylinder l The upperend of the cylinder is pivoted at |53 to the lighter-bar 84 adjacent theforward wall 2,.

Adjustment of the lighter bar may be accomplished by means of the handwheel which through the screw causes the piston to impart motion tothecylinder or in another way pressure may be applied between the pistonand upper end 0f the cylinder for actuating the lighter-bar.

` is mounted on a foundation or support and relationship and alignmentof components is diicult.

Left hand end portions |64 of the walls 2 and 4 extend upwardly and onouter sides are provided with pilasters |52 and a supporting platform|64 thereabove, see Figs. 1, 2 and 9.

The pilasters are U-shaped in horizontal cross section and have outervertical sides |68 and adjacent vertical sides llll and |12. Thesepilasters are 4formed from sheet metal and lower ends are welded to thesole plates 6 and 8. Vertical edges of the parts Il@ and |12 are weldedto the walls 2 and 4. Upper ends of the pilasters are welded to thehorizontal platform l 64.

Thus there is provided a strong rugged support for driving mechanismwhich in the form of the invention "shown, consists of a motor securedto a sub-base |82 which in turn is secured to the platform |64.

A shaft |84 of the motor has a grooved wheel |86 for a plurality ofbelts fixed thereto and a driven grooved wheel |88 is xed to the rollshaft 96. A plurality of endless driving bands or belts lull engage thepulleys |86 and |88 whereby the roll is driven by the motor.

The axis of the lighter-bar pivots, axis of rotation of roll 40 and axisof motor shaft |84 are so disposed that the driving tension of the bandsis not affected by up and down adjustments of the roll relative to thebed plate. That is, the longitudinal axes of the roll, motor shaft andpivot of the lighter bars are in substantially the same plane with theaxis of the roll between that of the motor shaft and lighter bar pivots.

Transverse struts |92 extend between the side walls 2 and 4 and aresecured by welding to the said walls and the platform |64, see Fig. 4.

An upper transverse wall |96 extends between and has opposite endswelded to the side walls 2 and 4. Said wall has a vertical lip portion|98 and a portion 290 extending upwardly and forwardly therefrom andthen downwardly and terminates in a substantially horizontal portion282, see Fig. 4.

An inlet member 204 extends through the platform |64 and is secured tosaid platform, to the member |92 adjacent thereto and to portion 20E) ofthe upper wall by welding. Said inlet has an opening 2&6 and a portion208 thereof is spaced from the lip |98 to provide a narrow passagewayElli. The opening Zilli may be connected to a water supply wherebywashing may be accomplished through the passageway 2 l D.

As in Fig 4, the upper end flange |04 of the cover |00 is secured tomember alle.

A back-fall wall 2|2 extends between the walls 2 and 4 and has itsopposite ends and lower end portions secured to said walls and the soleplates 6 and 8 by welding.

Thev lighter-bar caps 88 are provided with eyes 2|4 to which tackle maybe attached for assembling and disassembling purposes and likewise,although not shown, the cover or hood lill! may be provided with eyes.

As will be seen, the sole plates, front and midwall and varioustransversely extending walls secured together as they are provide astrong rigid structure with which the lighter-bar pillars, and adjustingmechanism is integral and in which the equalizer shaft and lighter barsare mounted and the various components operatively connected andmaintained in accurate align-- ment and operative relationship.

Thus there is provided a unitary, self-contained beater-refinermechanismadapted for' shipment to the mill of the purchaser. I nas-` much as thecomponents are tied together in ay unitary structure and in operativerelationship no special foundation structures are necessary for aligningand tying the components for theirI operation. The structure may be seton any sup-- port suitable for supporting the same and it islunnecessary to dispatch erectors to the destination of the mechanismsince the purchaser need. only set the mechanism on a support and con--struct the beater tub around and in conjunction with the mechanism.

As previously stated, it may be desired to employ plural units in amanner to perform a continuous process or successive steps in a process.in which case the purchaser may arrange the mechanisms as desired andconstruct the cooperating apparatus.

Where the mechanism is to be used in connection with a beater tub, themid-wall 4 may function as the mid-feather and beater walls may extendfrom the forward wall 2. The front bottom wall of the beater may extendfrom the right hand side of the channel 24 of lower transverse: wall 20and the back-fall may extend downward-y ly and to the left from theupper end of intermediate wall I4 as seen in Fig. 4.

The roll 40 will be rotated in the direction of the arrow in Fig. 4 forcoaction of the knives of said roll and of the bed plate. Any relativelyheavy objects in the material, particularly metal objects, such asbolts, nuts and the like, will be thrown by the roll into the transversechannel 24 thereby eliminating the possibility of injury to the knivesor bars of the roll and bed plate.

The invention may be embodied in other specific forms without departingfrom the essential characteristics thereof. Hence, the presentembodiments are therefore to be considered in all respects merely asbeing illustrative fand not as being restrictive, the scope of theinvention being indicated by the appended claims rather than 'by theforegoing description, and all modifications and variations as fallwithin the meaning and purview and range of equivalency of the appendedclaims are therefore intended to be embraced therein.
